Effects of Concentrations in Isocyanat-Alcohol-Systems
Thiele, Lothar
, p. 875 - 882 (1992)
The reaction between aromatic isocyanate and alcohol in nonpolar solvents at different alcohol and isocyanate concentrations and the effect of the presence of urethane in this solution at the start of the reaction have been examined.The results indicate that the rate constants of the observed second-order equation are dependent on the concentration of the reactants and of the urethane. Keywords.Association of alcohol and urethane; Spontaneous reaction; Urethane formation.
Photo-on-Demand Synthesis of Chloroformates with a Chloroform Solution Containing an Alcohol and Its One-Pot Conversion to Carbonates and Carbamates

Chloroformates are key reagents for synthesizing carbonates and carbamates. The present study reports a novel photo-on-demand in situ synthesis of chloroformates with a CHCl3 solution containing a primary alkyl alcohol. It further allowed the one-pot synthesis of carbonates and carbamates through subsequent addition of alcohols or amines, respectively.
Efficient preparation of carbamates by Rh-catalysed oxidative carbonylation: unveiling the role of the oxidant
Iturmendi, Amaia,Iglesias, Manuel,Munárriz, Julen,Polo, Victor,Pérez-Torrente, Jesús J.,Oro, Luis A.
, p. 404 - 407 (2017/01/03)
The synthesis of a wide variety of carbamates from amines, alcohols and carbon monoxide has been achieved by means of a Rh-catalysed oxidative carbonylation reaction that uses Oxone as a stoichiometric oxidant. In-depth studies on the reaction mechanism shed light on the intimate role of Oxone in the catalytic cycle.
Selenium-catalyzed oxidative carbonylation of aniline and alcohols to n-phenylcarbamates
Zhang, Xiaopeng,Jing, Huanzhi,Zhang, Guisheng
experimental part, p. 1614 - 1624 (2010/07/09)
A facile one-pot, phosgene-free synthesis of N-phenylcarbamates is demonstrated. Catalyzed by selenium, oxidative carbonylation of aniline with alcohols in the presence of carbon monoxide and oxygen affords the corresponding N-phenylcarbamates, mostly in fair to good yields. Selenium can be easily recovered because of its phase-transfer catalysis function. Copyright
